Java will never catch up to Scala, having to maintain backwards compatability for decades old code bases alone is anchor enough to keep Java in place relative to Scala. And Scala itself is evolving, the new compiler, Dotty, brings a host of new features[1] including union types, implicit functions, trait parameters, etc., all while improving compilation speeds and streamlining compiler internals. Add Scala Meta (overhauls old macro system), Scala Native joining Scala.js as Scala alt-JVM targets, and you have Java 28 ;) Saying that, Scala will likely remain a niche language, Java is king, slow and steady wins the race in the enterprise.
